Olivia Newton-John has taken to Twitter to quell reports of her imminent death. 

Newton-John, who was diagnosed with cancer for the third time in 2017, posted a video in which she says "rumours of my death have been greatly exaggerated." 

The 70-year-old singer says she's appreciative of fans reaching out to her as she fights cancer.

"I'm doing great. I want to wish you the happiest, healthiest 2019 that's possible. And thank you all for your wonderful love and support for me and for my Olivia Newton-John Cancer Wellness Center in Melbourne, Australia", said Newton-John.

In September 2018, Newton-John revealed that doctors found a tumour in her lower back. 

She was first diagnosed with breast cancer in 1992, and was diagnosed with breast cancer again in 2013.
